-/*
-   This is the AT91 MCI driver that has been tested with both MMC cards
-   and SD-cards.  Boards that support write protect are now supported.
-   The CCAT91SBC001 board does not support SD cards.
-
-   The three entry points are at91_mci_request, at91_mci_set_ios
-   and at91_mci_get_ro.
-
-   SET IOS
-     This configures the device to put it into the correct mode and clock speed
-     required.
-
-   MCI REQUEST
-     MCI request processes the commands sent in the mmc_request structure. This
-     can consist of a processing command and a stop command in the case of
-     multiple block transfers.
-
-     There are three main types of request, commands, reads and writes.
-
-     Commands are straight forward. The command is submitted to the controller and
-     the request function returns. When the controller generates an interrupt to indicate
-     the command is finished, the response to the command are read and the mmc_request_done
-     function called to end the request.
-
-     Reads and writes work in a similar manner to normal commands but involve the PDC (DMA)
-     controller to manage the transfers.
-
-     A read is done from the controller directly to the scatterlist passed in from the request.
-     Due to a bug in the AT91RM9200 controller, when a read is completed, all the words are byte
-     swapped in the scatterlist buffers.  AT91SAM926x are not affected by this bug.
-
-     The sequence of read interrupts is: ENDRX, RXBUFF, CMDRDY
-
-     A write is slightly different in that the bytes to write are read from the scatterlist
-     into a dma memory buffer (this is in case the source buffer should be read only). The
-     entire write buffer is then done from this single dma memory buffer.
-
-     The sequence of write interrupts is: ENDTX, TXBUFE, NOTBUSY, CMDRDY
-
-   GET RO
-     Gets the status of the write protect pin, if available.
